Chainguard, a cybersecurity firm providing secure-by-design infrastructure for software development and deployment, has raised $356m in a Series D funding round.
The investment was co-led by new investor Kleiner Perkins and existing backer IVP. Additional support came from new participants Salesforce Ventures and Datadog Ventures, along with all other existing investors. The round brings Chainguard’s total capital raised to $612m and values the company at $3.5bn.
Chainguard develops tools and platforms that allow organisations to build and maintain secure software supply chains. Its core offerings include Chainguard Containers, a secure container image product; Chainguard VMs, minimal virtual machines with no known vulnerabilities; and Chainguard Libraries, a Java-based secure language library suite.
The fresh capital will be used to enhance Chainguard’s entire product portfolio, scale its go-to-market operations, and fuel its international expansion in the EMEA and APAC regions. The company aims to continue meeting growing demand for secure open source solutions as it targets $100m in annual recurring revenue (ARR) by the end of fiscal 2026. In fiscal 2025, Chainguard’s ARR increased sevenfold to reach $40m.
The business has already attracted over 150 customers, including prominent global organisations such as ANZ Bank, Canva, GitLab, Hewlett Packard Enterprise, Oceaneering International, Snap Inc., Univar Solutions, VPBank, and Wiz.
Chainguard CEO and co-founder Dan Lorenc said, “Chainguard was founded on a simple yet powerful belief that security and innovation should go hand in hand. Today, Chainguard is paving the way for a future where secure, vulnerability-free open source software is the standard. In this next chapter of growth, we’re not just scaling our business – we’re fundamentally changing how software is built and secured from the ground up.”
Clients have praised Chainguard’s solutions for their role in strengthening cyber resilience. Dylan Shepard, senior lead platform engineer at Booz Allen, said, “In our work supporting the Department of Defense, security isn’t just a priority—it’s a mandate. Chainguard’s secure container images allow us to move fast while maintaining compliance with the most rigorous cybersecurity standards. By reducing the operational burden of patching and hardening, we can focus on delivering mission-critical solutions to our customers without compromising on security.”
Shrikant Pandhare, security engineering manager at Snap Inc., added, “At Snap, security is critical to maintaining the trust of our users and ensuring the integrity of our application. Chainguard’s secure container images help to drive down vulnerabilities and provide us with a solid technology foundation. This, in turn, enables us to focus on scaling and innovating rapidly to deliver new features and experiences for our users.”
